COMBINATION TOOL.

Original application filed October 26,1921, Serial No. 510,412. Dividedand this application filed J'anuary 1 '0 all whom it may concem:

Be it known that I, OSCAR A. SMITH, a citizen of the United States, residing at East Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Combination Tools, of whichthe following is a specifica tion.

This application is a division of ny copending application for multiple spindle lathes, Serial No. 510,412,filed October 26, 1921, and relates to combination tools particularly dc; signed and adapted. for use in connection with multiple spindle machines, an object thereof being to provide animproved tool of this character combining mechanisms for accomplishing a large numberof steps in thecomplete operation of turning out a finished article, such as for example a knurled nut, such mechanism including an improved organization and combination of side working tools and work stop, so constructed to operate in conjunction with .the end working tools of the machine as to perform a large number of steps in a single cycle of operation.

A furtherobject of this invention is to provide an improved combination tool comprising a tool holder adapted to carry one or more working tools, and a work stop also carried by the tool holder.

tion tool is provided, the same being adapted to be supported adjacent to. the work sup-.

porting means of the machine and also adapted to carry a-plurality of successively operating tools, thework stop being carried by the tool holder in predetermined relation to the tools.

Further objects of this invention will appear in the following description thereof, reference being had to the accompanying drawing forming a part of this specification,

wherein like reference characters indicate of suitable slots 84 V In the present instance a shiftable. side working combina-.

rollers 91.

Serial No. 529,930.

that my improved combination tool and work stop 7 8 comprises a suitable shank portion 80 terminating at its lower end inanenlarged body portion 81.. At the lower end' of this body portion 81 is mounted a work stop 82, the same having suitable tongues 83 cooperating with tongue-ways machined in the body portion,;the

parts being secured together for transverse-adjustment by means and screws 84. Thus, it

will be readily seen that the position of the stop slide 82 may be readily and effectively adjusted relatively to the tool holder and the work. This stop slide 82 is provided) with an integrally upwardly extending stop 85 which is adapted to act as a workstop proper. Above the stop slide the body portion 81 is cut'awayor recessed at each-side of the center thereof, as at 86*, for the purpose of housing a pair of adjustable slides 86. The latter are provided with suitable guide members 87 adapted to cooperate with guideways formed in the holder, the slides 86 being secured tothe body portion as by means-of bolts 88 and elongated slots 89 for adjustment relatively to eachother. In suitableslots 9O ma'chinedin the inner ends of these slides 86 and rotatably carried, asby means of suitable pivotscrews 90, are knurling tools 91, the'same being adjustable relatively to each other in accordancewith the size of the work. Carried in a suitable anthe front face of the spindle, is illustrated and in Fig. 2 the inner side ofthe combination tool, or in other words the side next to thework and the front face of the spindle, is shown. Thus, as shown in Fig. 3 the stop 85 is shown in position whereby the outer face thereof will besubstantially flush with the'outer faces of the knurling slides 86,,the

inner face of the stop being located outside the vertical plane of the knurling tools or It will be understood .of course that by loosening the bolts 88 the knurling rollers position by a suitable clamp gular slot directly above one of these knurl- V may be adjusted inany suitable relative position, so as to accommodate varying sizes of stock, and that by loosening the clamping plate 94 the cut-off and forming tools 92-93 may be adjusted as desired. Also by loosening the bolts 84 the stop slide 82 may be adjusted relatively to the work, the slots 8& being sufficiently elongated to permitsuch transverse adjustment. I

In operation it will be understood that the combination tool is suitably secured to the vertical or side working tool slide of the machine and that the combination tool is caused to travel downwardly so as to carry the stop 85 into roper operative positionso that when the work her is fed forward it will'come to a stop against the adjustable stop. After the work bar has been gripped by the chucking mechanism, the combination tool is again caused to travel downwardly so asto carry the knurlin'g'tools 91,

which have been adjusted laterally for size over the work bar'lOO to knurl the-same; At this time the desired travel of the combination tool is again arrested and the workba-r 100 is drilled as described in my copending application above mentioned. Thei'enpon the combination tool 78 is aga'n shifted downwardly and the-ctit-oli blade 92 comes in contact with the work bar, severing the finished kn'iirled nut from the work bar. The continued downwardtravel of the verticalsl'ide with the combination tool 78 car rie'sth-e beading or'grooving blade 93 into contact with the end of the barlOO protruding from the work spindle and forms the head or groove lOl-iir the work bar "for the s'uc'eeedingnutto beoperated upon after the bar is fed' forward again.

Ofcou rse it is understood that these cutoff and forming toolsorblades must be adjnstedand'spaced away from each other a proper distance, and that the blades are formed to a suitable shape for the desired work, andthat the knurling'tools are adjusted the proper spaced distance'relatire to each other,'andthat thestop 85 is also adjusted properly.
